Application filed August 2, 1915. Serial No. 43,261.

To all yzii/wm t may concern t Be it known that 1, JAMES MGSWEENEY, a citizen of the United States, residing at Crete, in the county of VayneVY and State of lVest Virginia, have invented a new and useful Plow, and Iv do hereby declare the following'to be a full, clear, and exactvdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved plow, and an object of the invention is to provide a device of this nature involving improved features of construction.

One of the features of construction is the provision of a plow beam having a slot therein and a rearwardly curved brace secured yin the slot, in combination with a plow standard pivoted to the rear end of the beam, and which standard has adjustable connections with the rearwardly extending curved brace.

Another feature of the invention is the provision of means of adjustably securing the shovel blade to the plow standard. Y

Another feature of the invention VVis the .provision of means for securing a cutter adjustably in :the slotf` of ythe Vplow beam.

1n practical fields the details of construc tion may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, Yas hereinafter set forth, shown in the drawings and claimed. l

In the drawings Figure 1 is a view in side elevation of the improved plow constructed in accordance with the invention. Fig. 2 is a plan view. Fig. 3 is a longitudinal sectional view on line 3 3 of Fig.`

2. Fig. 4 is a sectional view on line 4 4 of Fig. l. Fig. 5 is a sectional view on line 5 5 of Fig. 1. Fig. 6 is a sectional view on line 6 6 of Fig. 1.

Referring to the drawings 1 designates a plow beam having a vslot 2, and secured in one end of the slot is a rearwardly curved brace or member 3. A plow standard 4 is provided, which is provided with a bifurcation 5, to receive the rear end ofthe plow beam 1, there being a bolt 6 extending through the arms or sides 7 of the standard and through the beam 1, to pivot the standard to the beam. Handle members 8 are provided having their forward ends 9 se cured to the plow beam as at 10. These handle members extend rearwardly and outwardly and terminate in handles 11 and are provided with a transverse bracey 12. Braces 13 have their lower ends secured to the sides of the standard 4 by the bolt 6, and the upper ends of the braces 13 are adjustably secured by the bolts 14 and one of the apertures 15 (which apertures are formed in the braces 13)V to the handle members 8. The rearwardly curved brace 3 isprovided with aV plurality of apertures `16, any one of which is designed to receive the bolt 17, which extends transversely of the standard 4, so as to adustably connect the standard to the brace 3, which extends into the bifurcation of the standard. A shovel or blade 18 is secured to the lower end of the foot by the bolt 19. This bolt 19 has a rectangular portion 20, which passes through the rectangular apertureof the blade or shovel 1S, thereby preventing the shovel or blade from turning.l The rear edges of the sides of the standard 4 are provided with lnotches 22, to receive the right angled flange 23 of the plate 24, through which the bolt 19 extends, there being a nut 25 'on the bolt to clamp the plate 24 and the blade or shovel 18 in place. It isv to be observed that the platev24 may be moved vertically, so that the flange 23 will engage any two opposite notches 22, in view of which the shovel or blade 18 is adjustable with relation to the lower end of the foot.

The plate 24 has a tongue 26 provided withV a lateral portion 27 extending into the bifurcation of the standard, 'which lateral portion 27 has a rectangular aperture to receive the rectangular part of the bolt 19, to prevent the same from turning, hence preventing the blade or shovel 18 from turning. The brace 3 where it extends through the slot of the beam 1 has a lateral part 29, which enters the recess 30 of the filling block 31, which is also arranged in the slot 2 of the beam. A. second filling block 32 is arranged in the other end of the slot 2 of the beam 1, and is provided with a recess 33, to receive the part 34 of the beam to hold the filling block in position. Fitted between the lling block 31 and the wedge 36 is the up per shank 37 of the cutter 3S, which is provided with a cutting edge 39. This cutter 38 extends downwardly and forwardly, and is in advance of the blade or shovel 18, and

by virtue of the wedge 36, the shank of the cutter is held frictionally in vertical adjustable position. The wedge 36 is arranged between the shank 37 and the filling block 32, and has an upper cylindrical contracted portion or shank 40 to receive a threaded nut 41, to prevent downward displacement of the wedge. An elongated beam cap or plate 42 is mounted upon the beam 1, and has a slot 43 to receive the upper portions of each of the filling blocks and the shank 37 of the cutter 38, and partially receives the wedge. The nut 41 bears down against the opposite sides of the cap or plate 42, to prevent upward movement of the same. The rear end wall of the slot 43 of the plate 42 is beveled as shown at 44 to engage the under cut or bevel 45 of the upper end of the filling block 31, thereby also preventing upward displacement of the plate or cap 42, which is elongated. The rear end of the plate 42 is beveled as shown at 46, and which is engaged by the beveled surface 47 of the head 49 of the upper end of the curved brace 3, thereby preventing movement of the brace 3. The forward end of the beam 1 is provided with a suitable clevis, to which a suitable evener (not shown) is connected.

The invention having been set forth, what is claimed as new and useful is 1. In combination, a plow beam having an elongated slot and provided at its rear end with a supporting standard, a filling block in one end of the slot having a recess to receive a part of the beam, a brace extending into the other end of the slot and having its rear portion connected to the standard, a cutter having a shank extending vertically through the slot substantially midway thereof, the brace which connects to lthe standard having a lateral portion, a second filling block adjacent the shank of the cutter and having a recess engaging the lateral portion, a wedge between the shank of the cutter and the first filling block and having an upper threaded reduced part, a cap plate on the beam having a slot to receive the shank and the first land second filling blocks, means threaded on the reduced part of the wedgeto hold the cap plate and the wedge in position, the rear end of thecap plate partially overlying the upper end of the brace to hold the same in position.

2. In combination, a plow beam having a slot and provided at its rear end with a downwardly and forwardly extending supporting foot, a brace connected to the standard and extending into the slot having a head at its upper end, filling blocks in the slot, a cutter having a shank extending into the slot adjacent one filling block, and a wedge between the other filling block and the shanln and means to secure the wedge in position, said means including a plate to partially overlie the head of the brace of the standard to prevent movement of the same.

In testimony whereof I have signed my name to this specicationin the presence of two subscribing witnesses.
